Leaf spring assembly having leaf spring and at least one bearing bore retainer

Abstract

The invention relates to a leaf spring assembly with a leaf spring made of fiber composite material and a bearing hole holder, wherein the end of the leaf spring is positively received in the bearing hole holder in the longitudinal direction of the leaf spring In the retaining element, wherein the leaf spring has a length and a longitudinal middle surface, wherein the leaf spring has a cross-section along its length perpendicular to the longitudinal middle surface, in which width and height are over the entire length of the ends of the leaf spring is constant, wherein the end of the leaf spring is configured in a corrugated manner, wherein the holding element of the bearing hole holding device has a receptacle having a corrugated shape adapted to the end, wherein the end of the leaf spring There is a bellows, wherein the receptacle of the bearing bore holder is configured for receiving the bellows of the leaf spring. The leaf spring assembly is characterized in that the end of the leaf spring has two bellows, wherein the receptacle of the bearing bore holder is configured for positively fitting reception of the two bellows of the leaf spring.

Description

technical field [0001] The invention relates to a leaf spring assembly with a leaf spring made of fiber composite material and at least one bearing bore holder. Background technique [0002] Conventional leaf springs made of fiber composite material are usually designed uniformly over their entire longitudinal extent, so that they have a consistent fiber volume ratio over their entire longitudinal extent. For the non-positive connection of the leaf spring to the bearing hole holder, it is provided here that mechanical fastening elements, such as clamping sleeves or through-bolts, are provided, which pass both through the corresponding openings of the bearing hole holder and through the opening of the leaf spring. Corresponding openings are provided for non-positive connection of the leaf spring to the bearing bore holder. Such an assembly is described, for example, in EP 007 012 B. In this case, however, when dynamic loads occur when using such leaf spring assemblies, a re...

Problems solved by technology

In order to obtain leaf springs made of fiber composite material in these shapes, additional fibers have to be introduced or removed, so that a homogeneous fiber composite structure cannot be ensured in the end region of the leaf spring and in the spring region of the leaf spring
